Not sure if this is quite on topic for linux-kernel but I couldn't findanswers anywhere else so here goes:

I've got a couple systems where I've configured ttyS0 as a serialconsole. Everything works fine when a cable is plugged in and aterminal is listening on the other side. The kernel in question is2.4.20.

However, unplugging the cable and rebooting results in the boot processhanging. It appears that the kernel is waiting for the serial portacknoledge the fact that it is writing data.

What's strange is that this is a problem on one machine, but doesn'tappear to be a problem on another.

Anyone have any ideas on how to work around this issue besides leaving aterminal hooked up all the time?
